To determine which pair of angles is supplementary, let's analyze the angle relationships formed by the two parallel lines (s and t) cut by a transversal (the horizontal line).

In a situation where two parallel lines are intersected by a transversal, supplementary angle pairs can be identified in the following ways:

  1. Linear pairs: Two angles that are adjacent and whose non-common sides form a straight line.
  2. Consecutive interior angles: Two angles on the same side of the transversal that are interior to the parallel lines.

Given your options, the most appropriate choice is:

∠G and ∠D because they are a linear pair.

This is correct because ∠G and ∠D are adjacent (they share a common vertex and side) and their non-common sides form a straight line, making them supplementary (their measures add up to 180 degrees).
